THREAD GUIDE FOR TEXTILE Mater-[runs Application filed February 28, 1922. Serial No. 539,944. I

T 0 all whom it may concern Be it known that I, FREEMAN Cass, a

citizen of the United States, residing at guide and into the-other parts of the machine. The object of this invention is to provide a guide having the walls of the eye arranged so as to form angles or sharp V- shaped corners in the eye so that whenever knots or slugs occur in the silk thread passing through the guide they will be caught by the guide and the silk broken down. A guide such as that ofthe present invention will, to a considerable extent, prevent the passage of knots on the thread.

In the accompanying drawing there is illustrated in elevation and partly in section a-thread guide embodying the present invention. v

The guide, as shown in the drawing, comprises a'body 10, provided at its lower end with a-recess or socket 11-. in which a supporting wire 12;is secured, The upper portion of the body is provided with an elongated eye 13 which comprises an upper por-v tion l t and a lower portion 15 which are connected'by a narrow passageway 16. An

inlet slot 17 extends upwardly and inwardly v and communicates with the lower portion 15 of the eye. The rear wall 18 of the eye 13 or in other words the wall opposite the inlet slot 17 is preferably made straight and arranged substantially vertically. The upper wall 19 of the upper portion of the eye is arranged at an acute angle to the wall 18 whereby a sharp V-shaped corner is formed at the point 20 in the upper portion of the eye. The bottom wall 21 of the lower por-,

tion of the eye is also arranged at an acute angle to the wall 18 whereby there is formed I a sharp V-shaped corner 22 at thebottom of the lower eye. The wall 19, it will be observed, extends forwardly and downwardly while the wall 21 extends forwardly and upwardly. The upper portion of the eyevis said body having an inlet slot comrnunicatalso provided with a wall 23 which is ar;

ranged at an angle with the wall 19 whereby a second sharp corner 24 is provided in the upper portion of the eye. The material of the body 10 above the slot 17 extends toward the vertical wall 18 to provide the, narrow passage way 16 heretofore described.

In the operation of the device the thread normally rests in the upper eye and in passing through the same will naturally lie in' one of the sharp corners of this portion of the eye. The result'is that any knotsin the thread will be caught as the thread passes through the eye. 1 In case the thread, 'due' to vibrationv of the same, drops out of the upper portion of the eye it will be caught by a the lower portion thereof and will then normally lie in the sharp corner 22 of the lower portion of the eye.

What I claim as my invention anddesire to secure by Letters Patent is:

1.;Athread guide for textile machines I comprising a body having an eye provided with a substantially straight rear wall, said eye consisting of an upper portion and a lower portion with a narrow passageway connecting the same, the upper wall. of said upper portion and the lower wall of-said 2 lower portion of the eye being arranged at an acute angle to said rear wall, whereby a sharp corner is formed at the top and bot tom of said eye, and an inlet slot com- 1 muhicating with said lower portion of the eye opposite said rear Wall.

comprising a body having an eye provided with a substantially straight rearwa1l,tha t portion of the body in front of theeye being provided with apart extending rearwardly into close proximity to saidrear wall whereby said eye is divided into an upper portion and a lower portion with a narrow passage connecting the same, the-upper wall of'said upper portion of the eye andthe each being arranged at an acuteangle to I lower wall of said lower P01131011 of the eye 7 said rear wall, whereby awsharp corner is formed at the-top and bottom of said eye,

ing with said lower portion of the eye above the lower end .of said rear wall. the upper wall of said inlet slot being inclined down- Y wardly'and outwardly from said narrow pas-' sage to the front edge of said body substa-ntially as described'l.
